Connect to Android via USB by adb in Linux

Add udev rule for fix permission issues:

$ cat /etc/udev/rules.d/90-android.rules

# Standard Google device.
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0c03", MODE="0666", GROUP="plugdev"
# China N101 II
SUBSYSTEM=="usb", ATTR{idVendor}=="2207", ATTR{idProduct}=="0010", MODE="0666", GROUP="plugdev"

Reload udev rules and re-plug device via USB:

$ sudo service udev force-reload

See:

http://developer.android.com/tools/device.html

Connect to Android via USB by adb in Windows

Get latest official Google drivers from:

https://developer.android.com/studio/run/win-usb.html
Get the Google USB Driver.

If your device isn't in official list you can try to find driver in Windows update catalog at http://www.catalog.update.microsoft.com.

Use search by vendor or device name, or string adb. Alternatively use hardware id.

BTW older version of official Google drivers are also in Windows update catalog.

Most probably you will fail to find drivers for numerous Chinese/noname Android devices. We can reuse official Google drivers. To do that:

Note

As you see Google's adb driver works fine with any Android phone. It's Microsoft policy to forbid class drivers so each vendor is required to provide same driver with different hardware ID and to pay money for Windows Logo® program and signing process.

Tip

bcdedit can be run with alternative options:

cmd# bcdedit.exe /set nointegritychecks on
cmd# bcdedit.exe /set nointegritychecks off
